What 3d51 means on a Maytag oven

Error code 3d51 on a Maytag oven indicates that the UH control board has detected a meat probe calibration value that falls outside the acceptable range. The UH control performs an internal check on the meat probe's calibration data, and when that stored value does not meet the expected parameters, the board flags this fault. Because the calibration data is stored and processed within the control board itself, the board is both the component running the check and the likely source of the failure.

For homeowners, this means the oven's control system cannot properly read or trust the meat probe temperature sensor. The meat probe is the plug-in thermometer you insert into food to monitor internal cooking temperature. When the control board loses confidence in the probe's calibration, it throws this code to prevent inaccurate temperature readings from affecting your cooking. The probe itself may be fine; the problem is more likely in how the control board is storing or processing the calibration data.

This code is specific to ovens equipped with the UH control board. A corrupted or failed control board is the primary suspect, as the calibration values for the meat probe are managed internally by the board. Replacing the control board is the recommended first step to resolve this fault.

Common causes of 3d51

  1. 01

    Failed or corrupted UH control board

    Part replacement

    The UH control board stores and validates the meat probe calibration value internally. If the board's memory or firmware has corrupted or the board has failed, it can no longer maintain a valid calibration value, triggering error 3d51.

  2. 02

    Meat probe with out-of-spec resistance output

    Part replacement

    If the meat probe itself sends a signal outside the range the UH control expects during its calibration check, the board may log this fault. A damaged or degraded probe can produce readings that fail the calibration validation.

  3. 03

    Damaged or shorted meat probe port wiring

    Part replacement

    Wiring between the meat probe receptacle and the UH control board can become damaged from heat exposure or physical wear. A short or open in this circuit can present as an out-of-range calibration value to the control board.

Frequently asked questions about 3d51

What does error code 3d51 mean on a Maytag oven?
Error code 3d51 means the UH control board has detected that the meat probe calibration value is outside the acceptable range. This code is specific to Maytag ovens equipped with the UH control. The board checks the calibration data it stores for the meat probe, and when that data fails the check, it displays this fault. The control board is the most likely failed component.
How do I fix error code 3d51 on a Maytag oven?
The first and primary fix for error code 3d51 is replacing the UH control board. Because the calibration value is stored and managed by the control board, a failed or corrupted board is the most common cause. If replacing the control board does not resolve the fault, inspect the meat probe itself and the wiring between the probe receptacle and the board for damage. A replacement meat probe is a lower-cost secondary step if the control board swap does not clear the code.
Can I still use my Maytag oven if it shows error code 3d51?
You can generally continue using the oven's standard bake and broil functions while 3d51 is active, since the error is specific to the meat probe calibration system. However, you should not rely on the meat probe to monitor food temperatures while this code is present, as the readings may be inaccurate or non-functional. Resolve the fault before using the probe for food safety reasons.
How much does it cost to fix error code 3d51 on a Maytag oven?
A replacement UH control board for a Maytag oven typically costs between $150 and $350 for the part alone, depending on the specific model. If you hire a technician, labor costs generally add $100 to $200 on top of the part price. Replacing the control board is a moderately involved repair requiring electrical disconnect and careful handling of wiring harnesses; experienced DIYers can complete it, but those unfamiliar with appliance electronics should have a technician handle it.
Could the meat probe itself cause error code 3d51, or is it always the control board?
The meat probe can contribute to error code 3d51 if the probe's output falls outside the range the UH control board expects during its calibration check. However, since the calibration value is stored internally on the control board, a failed board is the more likely cause and the recommended first replacement. If swapping the control board does not clear the fault, test or replace the meat probe and inspect the probe port wiring before assuming further diagnosis is needed.
